USGS Introduces a National Approach to Coastal Change Hazards (CCH) Science
New Study Finds the Restoration of Forests with Active Rapid ʻŌhiʻa Death Infections May Be Possible
Hilo, Hawaiʻi – For the first time, researchers have shown that native ʻōhiʻa seedlings can survive for at least a year in areas that have active mortality from Rapid ʻŌhiʻa Death, or ROD, a fungal disease that is devastating to this dominant and culturally important tree in Hawaiian forests. This information can be useful to land managers and homeowners as they prioritize conservation actions.
Keeping Track of "Caly"
Caly isn't likely to wonder off off, but with a remote camera and monitoring station online 24-hours a day, USGS and partners at the State of Hawai‘i Division of Forestry and Wildlife, University of Hawai‘i, and the USFWS can learn how an extremely rare plant is responding to changes in environmental conditions.

Population density, distribution, and trends of landbirds in the National Park of American Samoa, Ta‘ū and Tutuila Units (2011–2018)
The National Park of American Samoa (NPSA) was surveyed for landbirds from June through July, 2018. Surveys were conducted using point-transect distance sampling methods to estimate bird densities. This information provides the second datum in the time-series of landbird monitoring for long-term trends in landbird distribution, density, and...
Judge, Seth; Camp, Richard J.; Vaivai, Visa; Hart, Patrick J. Automated telemetry reveals post-reintroduction exploratory behavior and movement patterns of an endangered corvid, ʻAlalā (Corvus hawaiiensis) in Hawaiʻi, USA
Continuous movement monitoring is a powerful tool for evaluating reintroduction techniques and assessing how well reintroduced animals are adjusting to the wild. However, to date, continuous monitoring has only occurred for large-bodied species capable of carrying heavy tracking devices. In this study we used an automated VHF radio...
Smetzer, Jennifer R; Greggor, Alison L; Paxton, Kristina L.; Masuda, Bryce M; Paxton, Eben H. Understanding metrics of stress in the context of invasion history: The case of the brown treesnake (Boiga irregularis)
Invasive species can exert rapid depletion of resources after introduction and, in turn, affect their own population density. Additionally, management actions can have direct and indirect effects on demography. Physiological variables can predict demographic change but are often restricted to snapshots-in-time and delayed confirmation of changes...
